Definitions
- Cold compression therapy is used in sports medicine and injury rehabilitation. More particularly, cold compression therapy may be used for injuries related to soft tissue trauma such as post-surgical rehabilitation, sports injuries, or arthritic conditions, for instance.
- Cold compression therapy is a combination of cryotherapy and compression therapy.
- Cryotherapy generally includes treatment of an injury through direct application of cold temperatures to the injured area. By applying the cold temperatures, heat is transferred away from the injured area, which causes vasoconstriction and reflexive vasodilation, which decreases metabolism and may alleviate minor pain.
- Cryotherapy systems include a wide range of devices from a bag of ice to cryo-saunas in which a user can enter and sit for some time to treat an entire body of the user.
- Compression therapy generally refers to exerting an external pressure on an injured area.
- the external pressure acts on the tissue to decrease or prevent swelling.
- compression systems include a wide range of devices from stretchy socks to wraps with complex geometric design having hook and loop systems for securing the wraps to the injured area.
- some cold compression systems are dynamic. Dynamic cold compression systems allow adjustment of the external pressure. However, dynamic adjustment systems often require large-scale compressors with complex controls to allow a user to control the external pressure applied to the injured area. These systems are large, expensive, and cumbersome to operate. The majority of dynamic cold compression systems are not practical for individual use due to the expense and difficulty involved in proper use. Thus, these cold compression systems are used by physical therapists.
- Disclosed embodiments are generally concerned with a therapy system that enables a user to apply a thermal pack, such as a cold pack or a heat pack, or other therapeutic element, such as a TENS device, to an affected area while, also enabling the user to apply and maintain an external pressure to the affected area.
- a thermal pack such as a cold pack or a heat pack
- other therapeutic element such as a TENS device
- the applied external pressure may be adjusted by the user.
- Embodiments within the scope of this disclosure may include any one or more of the following elements, and features of elements, in any combination: a layer having first and second ends and configured to be wrapped around a portion of the anatomy of a user; a sleeve configured to removable receive a portion of the anatomy of a user; a cold pack; a therapeutic element, which may take the form of any of a heat pack, cold pack, TENS device, or water circulation pad; a layer having first and second ends and configured to be wrapped around a portion of the anatomy of a user, and the layer includes an elastic portion; a sleeve configured to removably receive a portion of the anatomy of a user, and the sleeve may optionally include an elastic portion; one or more cold packs; one or more heat packs; a cold compress; a cold water circulation system including a water circulation pad; an adjustable tightening mechanism operable by a user to vary an external pressure exerted by a layer or sleeve on a portion of the anatomy of the
- a system comprising: an inner layer, the inner layer being continuous between a first end and a second end of the cryotherapy system and configured such that the inner layer can be configured to define an opening through which an extremity of a user may be introduced; an outer layer attached to the inner layer, the outer layer including a first portion of the outer layer and a second portion of the outer layer; a cold pack positioned between the inner layer and the outer layer; and a tightening mechanism configured to move the first portion of the outer layer towards the second portion of the outer layer and to maintain the first portion with respect to the second portion, thereby pressing the cold pack against the inner layer and applying therapeutic compression to the extremity.
- the tightening mechanism includes: a lace; a first lace retainer secured on the first portion, the lace routed through the first lace retainer; a second lace retainer secured on the second portion, the lace routed through the second lace retainer; and a lace tensioner configured to apply tension to the lace and to retract the lace, which moves the first lace retainer towards the second lace retainer.
- the tightening mechanism includes: a lace; a first plurality of lace retainers secured on the first portion, the lace routed through each of the first plurality of lace retainer; a second plurality of lace retainers secured on the second portion, the lace routed through each of the second plurality of lace retainers; and a lace tensioner configured to apply tension to the lace and to retract the lace which moves the first lace retainer towards the second lace retainer.
- each of the first plurality of lace retainers and each of the second plurality of lace retainers are U shaped and include an inlet and an outlet oriented substantially perpendicular to an edge of the first portion and a length oriented substantially parallel to the edge of the first portion.
- first plurality of lace retainers and the second plurality of lace retainers include a proximate lace retainer positioned nearest a core of a user; the first plurality of lace retainers and the second plurality of lace retainers include a distal lace retainer positioned farthest from the core of the user; and when the tightening mechanism moves the first portion of the outer layer towards the second portion of the outer layer, the distal lace retainers move together before the proximate lace retainer.
- each of the first plurality of lace retainers is separated from adjacent lace retainers of the first plurality of lace retainers by a constant distance; and each of the second plurality of lace retainers is separated from adjacent lace retainers of the second plurality of lace retainers by the constant distance.
- a system comprising: a layer of material configured to at least partially surround an extremity of a user, the layer having a first state in which the layer of material is secured to the extremity and applies a first external pressure to the extremity, and a second state in which a second external pressure is applied to the extremity; and a tightening mechanism configured to transition the layer from the first state to the second state.
- a system comprising: a plurality of layers configured to be applied to in a first arrangement and a second arrangement to an extremity of a user, the first arrangement including the extremity being introduced into an opening defined when at least one of the plurality of layers is secured to the user and a separation in another of the plurality of layers has a first dimension, and the second arrangement including the other layer in tension such that the separation in the other layer has a reduced dimension, which constricts at least one dimension of the opening.
- the tightening mechanism includes: a pull-and-lock mechanism; a wind and tuck mechanism; a jam cleat; or a rotate-and-lock mechanism.
- securing mechanism includes a set of buttons, a set of snaps, a belt tightening system, metal hooks, or a hoop and loop system.
- TENS transcutaneous electrical nerve stimulation
- a method of cryotherapy comprising: introducing an extremity into an opening defined by a layer of material; securing the layer of material to the extremity such that a first pressure is applied to an injured area; and operating a tightening mechanism such that a second pressure is applied to the injured area.

Abstract
Description
- This application hereby claims priority to U.S. Provisional Patent Application Ser. No. 61/786,354, entitled CRYOTHERAPY COMPRESSION SYSTEM, filed Mar. 15, 2013, and incorporated herein in its entirety by this reference.
- The embodiments discussed herein are related to cryotherapy.
- Cold compression therapy is used in sports medicine and injury rehabilitation. More particularly, cold compression therapy may be used for injuries related to soft tissue trauma such as post-surgical rehabilitation, sports injuries, or arthritic conditions, for instance.
- Cold compression therapy is a combination of cryotherapy and compression therapy. Cryotherapy generally includes treatment of an injury through direct application of cold temperatures to the injured area. By applying the cold temperatures, heat is transferred away from the injured area, which causes vasoconstriction and reflexive vasodilation, which decreases metabolism and may alleviate minor pain. Cryotherapy systems include a wide range of devices from a bag of ice to cryo-saunas in which a user can enter and sit for some time to treat an entire body of the user.
- Compression therapy generally refers to exerting an external pressure on an injured area. The external pressure acts on the tissue to decrease or prevent swelling. Like cryotherapy systems, compression systems include a wide range of devices from stretchy socks to wraps with complex geometric design having hook and loop systems for securing the wraps to the injured area.
- Most existing cold compression therapy systems combine application of cold temperatures with application of external pressure. Some of the cold compression systems are static. Users of static cold compression systems cannot adjust or quickly alleviate the external pressure exerted on the injured area. These static cold compression systems are not intended to be adjusted and often require substantial re-positioning and modifications to various straps to change the external pressure.
- Alternatively, some cold compression systems are dynamic. Dynamic cold compression systems allow adjustment of the external pressure. However, dynamic adjustment systems often require large-scale compressors with complex controls to allow a user to control the external pressure applied to the injured area. These systems are large, expensive, and cumbersome to operate. The majority of dynamic cold compression systems are not practical for individual use due to the expense and difficulty involved in proper use. Thus, these cold compression systems are used by physical therapists.
- The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one example technology area where some embodiments described herein may be practiced.
- It should be noted that the embodiments disclosed herein do not constitute an exhaustive summary of all possible embodiments, nor does this brief summary constitute an exhaustive list of all aspects of any particular embodiment(s). Rather, this brief summary simply presents selected aspects of some example embodiments. It should be noted that nothing herein should be construed as constituting an essential or indispensable element of any invention or embodiment. Rather, various aspects of the disclosed embodiments may be combined in a variety of ways so as to define yet further embodiments. Such further embodiments are considered as being within the scope of this disclosure. As well, none of the embodiments embraced within the scope of this disclosure should be construed as resolving, or being limited to the resolution of, any particular problem(s). Nor should such embodiments be construed to implement, or be limited to implementation of, any particular technical effect(s) or solution(s).
- Disclosed embodiments are generally concerned with a therapy system that enables a user to apply a thermal pack, such as a cold pack or a heat pack, or other therapeutic element, such as a TENS device, to an affected area while, also enabling the user to apply and maintain an external pressure to the affected area.

FIGS. 1A-1D illustrate anexample cryotherapy system 100 according to some embodiments described herein. Specifically,FIG. 1A is an external view of thecryotherapy system 100 apart from a user and unwrapped.FIG. 1B is a sectional view of thecryotherapy system 100 in a wrapped, but unsecured configuration.FIG. 1C is thecryotherapy system 100 worn by a user 104 (FIG. 1C only).FIG. 1D is thecryotherapy system 100 exploded into some individual components. It should be appreciated that a detailed description of thecryotherapy system 100 is provided herein, however this description and principles thereof may be applicable to other embodiments, which may include some dissimilar and/or some additional features. - Generally, the
cryotherapy system 100 enables a user to apply a cold pack while further applying and maintaining an adjustable external pressure to an injured area. The adjustable external pressure may be controlled manually by theuser 104. In some embodiments, thecryotherapy system 100 may be self-contained. Thus, in these and other embodiments, one or more external systems such as external electrical systems, water-cooling systems, and/or water circulation systems may be unnecessary. The manual control may simplify thecryotherapy system 100 and reduce the expense and training required to operate thecryotherapy system 100. - With reference to
FIGS. 1A-1D , thecryotherapy system 100 may include aninner layer 102. Theinner layer 102 is a continuous layer extending from afirst end 150 to a second end 152 (FIG. 1A only). Additionally theinner layer 102 may be configured to be placed adjacent to theuser 104. For example, theinner layer 102 may be placed directly on skin of theuser 104 or theuser 104 may place a towel between the skin of theuser 104 and theinner layer 102. Theinner layer 102 depicted inFIGS. 1A-1D is substantially rectangular. However, this is not meant to be limiting. The general shape of theinner layer 102 may take an anatomical shape. For instances, some embodiments of thecryotherapy system 100 may be configured to be worn during some activity. Accordingly, these embodiments may be configured with one or more sections removed to allow for such activity. - With continued reference now to the particular example of
FIGS. 1A-1D , theinner layer 102 is configured such that when secured to theuser 104, theinner layer 102 defines an opening 106 (FIGS. 1B and 1C only). Theopening 106 is configured such that an extremity of theuser 104 may be introduced into theopening 106. In some embodiments, introduction of the extremity into theopening 106 may occur while theinner layer 102 is being secured to theuser 104. With the extremity of theuser 104 introduced into theopening 106, thecryotherapy system 100 is positioned around an injured area of theuser 104. In this configuration, theuser 104 can generally position thecryotherapy system 100 on the injured area or adjust the position of thecryotherapy system 100 to increase comfort. For example, inFIG. 1C , a leg of theuser 104 is introduced into theopening 106. In this configuration, theuser 104 may position thecryotherapy system 100 such that thecryotherapy system 100 is fit around the knee of theuser 104. - The
opening 106 may be substantially cylindrical, as depicted inFIGS. 1A-1D , or may take a more complex shape. Some additional examples of theopening 106 with more complex shapes are provided with reference toFIGS. 14-19B . - The
cryotherapy system 100 may include asecuring mechanism 108. The securing mechanism may be used to define theopening 106 and to secure thecryotherapy system 100 to theuser 104. Thesecuring mechanism 108 depicted inFIGS. 1A-1D is a hook and loop system. However, this is not meant to be limiting. - Referring to
FIGS. 8A-8C , some example securing mechanisms that may be implemented in thecryotherapy system 100 ofFIGS. 1A-1D are illustrated. In each ofFIGS. 8A-8C , two ends (i.e., 150 and 152 ofFIG. 1A ) of the cryotherapy system are depicted without a center section. Thesecuring mechanism 108 discussed with reference toFIGS. 1A-1D may alternatively include one or more metal hooks 802 (108A) as depicted inFIG. 8A , a set ofsnaps 806/808 (108B) as depicted inFIG. 8B , or abelt tightening system 810/812 (108C) as depicted inFIG. 8C (These securingmechanisms securing mechanism 108 ofFIGS. 1A-1D are generally referred to as securing mechanisms 108). - In some alternative embodiments, securing
mechanism 108 may include a set of buttons, a binding or tethering system, or another suitable mechanism that may perform the functions described herein. - In each of
FIGS. 8A-8C and as best illustrated inFIG. 1D , the securingmechanisms 108 include components that allow some adjustability when securing thecryotherapy system 100 to theuser 104. For example, inFIG. 8A , the metal hooks 802 may be secured withinmultiple hook receivers 804. Thehook receivers 804 are positioned in three separate rows, which allow three separate dimensions for theopening 106. Consequently, thecryotherapy system 100 may be positioned on theuser 104 on an injured area and may be adjusted for the comfort of theuser 104. - Similar to the metal hooks 108A, the set of
snaps 108B inFIG. 8B includessnaps 806 andmultiple snap receivers 808. Themultiple snap receivers 808 are positioned in multiple rows, which allows adjustability in securing thecryotherapy system 100 to theuser 104. Likewise, thebelt tightening system 108C depicted inFIG. 8C includesbelts 810 that are run throughmultiple buckles 812, which allows thebelts 810 to be tightened. Additionally, thesecuring mechanism 108 ofFIGS. 1A-1D includes multiple strips of hooks and multiple strips of loops that allow adjustment in the dimensions of theopening 106 and thus an adjustable fit of thecryotherapy system 100 on theuser 104. By including some adjustability, an external pressure may be applied with little constriction of thecryotherapy system 100. - Alternatively, in some embodiments, the
cryotherapy system 100 does not include asecuring mechanism 108. For example,FIGS. 6A and 6B illustrate an embodiment of thecryotherapy system 100 that does not include asecuring mechanism 108, which is referred to herein as asleeve cryotherapy system 600. In these and other embodiments, thesleeve cryotherapy system 600 may be sized to fit a particular subset of users, e.g., small, medium, and large. Some additional details of asleeve cryotherapy system 600 ofFIGS. 6A and 6B are included below. - Referring back to
FIGS. 1A-1D , thecryotherapy system 100 also includes anouter layer 110. Theouter layer 110 further includes afirst portion 112 and asecond portion 114 which are interrupted by aseparation 116. Theouter layer 110 is attached to theinner layer 102 at thefirst portion 112 and thesecond portion 114 but not at theseparation 116. For example, thefirst portion 112 and thesecond portion 114 of theouter layer 110 may be sewn to, adhered to, or otherwise attached to theinner layer 102. Thus, theseparation 116 may be spanned by a piece of fabric and/or other material (the “spanning material”) and the spanning material, in some embodiments at least, comprises an element of the compression layer. In yet other embodiments, the spanning material is not part of the compression layer and, instead is part of a layer situated inside of the compression layer. - Additionally, as best illustrated in
FIGS. 1A-1C thesecuring mechanism 108 may be at least partially attached to theouter layer 110. For example, referring toFIG. 1B , when thecryotherapy system 100 is secured to theuser 104 thefirst portion 112 may include one of the hooks or the loops and thesecond portion 114 may include the other of the hooks and the loops. Theuser 104 can thus wrap thecryotherapy system 100 around an extremity such that thefirst portion 112 overlaps thesecond portion 114 where thesecuring mechanism 108 is located. - The
cryotherapy system 100 also includes a cold pack 118 (FIGS. 1B and 1D only). Thecold pack 118 may be positioned between theinner layer 102 and theouter layer 110. Thecold pack 118 may include, but is not limited to, a reusable self-contained chemical cold compress, a thermodynamic gel, a bag that may be filled with water, a bag that can be filled with ice, or a cold therapy water circulation system. - As illustrated in
FIG. 1D , thecold pack 118 may be removable. In these embodiments, theinner layer 102 may include a zipper or hook and loop system to secure thecold pack 118 within theinner layer 102. Additionally, in these and other embodiments, thecold pack 118 may be removed and frozen then placed in theinner layer 102 before thecryotherapy system 100 is secured to theuser 104. Alternatively, thecold pack 118 may be sewn into theinner layer 102. In these and other embodiments, theentire cryotherapy system 100 may be frozen prior to securing thecryotherapy system 100 to theuser 104. Moreover, and as noted elsewhere herein, thecold pack 118 need not be employed in every case, and thecryotherapy system 100 can be used to provide compression only. - The
cryotherapy system 100 also includes atightening mechanism 200. In general, and as disclosed in more detail elsewhere herein, embodiments of a tightening mechanism, including theexample tightening mechanism 200, are configured and operable to effect translational motion of one part of a device, such ascryotherapy system 100 for example, relative to another part of the device. The static portion of such an arrangement may comprise a first layer or sleeve, and the moving portion of such an arrangement may comprise a second layer, which can be a compression layer for example. The moving portion of the layer may also translate relative to a therapeutic device and/or one or more other layers of the device. In another example, only a single layer is used, and a tightening mechanism is configured and operable to effect translational movement of one portion of that layer relative to another portion of that layer. It should be noted that, as used herein, the compression layer refers to the layer whose portion, or portions, are moved by a tightening mechanism. - As well, this disclosure contemplates that any device, such as the
cryotherapy system 100 for example, within the scope of this disclosure may include multiple tightening mechanisms, such as theexample tightening mechanism 200. Such an arrangement may be useful where, for example, there is a need to exert different levels of compression on different portions of the anatomy of a user. By employing multiple, independently controllable, tightening mechanisms, even where a single tightening mechanism might otherwise suffice, such devices enable the implementation of highly customizable, and adjustable, compression schemes. As well, desirable useful therapeutic effects may be achieved in some instances by tightening the multiple tightening mechanisms in a particular order. For example, if multiple tightening mechanisms are to be used to compress a portion of the leg of a user, it may be desirable to tighten a tightening mechanism near the ankle of the user prior to tightening a tightening mechanism near the upper calf of the user. The multiple tightening mechanisms used in devices that include them may be the same as each other, or may be different from each other. - With the foregoing points in mind, details are now provided concerning some example tightening mechanisms, one of which is the
tightening mechanism 200. In this particular example, thetightening mechanism 200 is configured and operable to move thefirst portion 112 of theouter layer 110 towards thesecond portion 114 of theouter layer 110, such that thefirst portion 112 slides along the outside of thecold pack 118. By moving thefirst portion 112 towards thesecond portion 114 thecold pack 118 is pressed againstinner layer 102, and an external pressure is applied to theuser 104. The external pressure may be a therapeutic compression and the external pressure may press thecold pack 118 against the extremity of theuser 104 to increase thermodynamic transfer from the extremity of theuser 104. - Additionally, the
tightening mechanism 200 is configured to maintain the position of thefirst portion 112 with respect to thesecond portion 114. Thus, when theuser 104 applies the external pressure, thetightening mechanism 200 holds a constant or semi-constant external pressure on the injured area. By maintaining thefirst portion 112 with respect to thesecond portion 114, the therapeutic benefits of the external pressure and the thermodynamic transfer is applied for a controllable duration without additional efforts by theuser 104. - Referring to
FIG. 1C , an overview of an example function of thecryotherapy system 100 is illustrated. Thecryotherapy system 100 may be applied to theuser 104 in a first arrangement. In the first arrangement, thetightening mechanism 200 is loose (i.e., theseparation 116 is at its greatest dimension), allowing theuser 104 to introduce an extremity in to theopening 106. In the first arrangement, theuser 104 may generally position thecryotherapy system 100 over an injured area. - The
user 104 then tightens thetightening mechanism 200, which moves thefirst portion 112 of theouter layer 110 towards thesecond portion 114 of theouter layer 110. Thetightening mechanism 200 places theouter layer 110 in tension, reduces the dimension of theseparation 116, and reduces the dimension of theopening 106. Due to the reduction in the dimension of theopening 106, an external pressure is imposed on the extremity introduced into theopening 106. -
FIG. 2 illustrates anexample tightening mechanism 200 that may be implemented in thecryotherapy system 100 ofFIGS. 1A-1D . Thetightening mechanism 200 may be implemented, for example, on theouter layer 110 of thecryotherapy system 100 ofFIGS. 1A-1D . Some examples of such a tightening mechanism include tightening mechanisms by Boa Technology, Inc. (http://www.boatechnology.com/), although other tightening mechanisms can alternatively be employed. - It will be appreciated from the present disclosure that the example tightening mechanisms disclosed herein are example structural embodiments of a means for applying and controlling pressure, and any other structural element(s) capable of performing one or more aspects of the functionality of the disclosed tightening mechanisms may alternatively be employed and are considered to be within the scope of this disclosure.
- Generally, the
tightening mechanism 200 includes alace 206 that is routed through one ormore lace retainers 208. Some of thelace retainers 208 are positioned on afirst portion 210 and the other lace retainers are positioned on asecond portion 212. Thelace 206 is retracted by alace tensioner 204. As thelace 206 is refracted, tension is applied to thelace retainers 208, moving thefirst portion 210 towards thesecond portion 212. - In
FIG. 2 , thelace tensioner 204 includes a rotate-and-lock mechanism 228. The rotate-and-lock mechanism 228 may enable a user to rotate an external piece that winds thelace 206. As thelace 206 is wound, the rotate-and-lock mechanism 228 maintains thelace 206 until released by the user. In some embodiments, the rotate-and-lock mechanism 228 may be geared such that one rotation of the external piece results in multiple rotations of a spool on which thelace 206 is wound. - Embodiments of the
tightening mechanism 200 are not limited to a rotate-and-lock mechanism 228.FIGS. 3A-3C illustrateexample lace tensioners FIG. 2 . Each of the lace tensioners 300 may be included in a tightening mechanism, which is similar to the general configuration described above with respect toFIG. 2 . To apply tension to thelace 206, each of the lace tensioners 300 retract thelace 206 and maintain the position of thelace 206 as refracted until released by a user. - Specifically,
FIG. 3A depicts a pull-and-lock mechanism 300A that may be implemented as a lace tensioner. To apply tension to thelace 206, the user pulls as indicated byarrow 302. As thelace 206 moves through a locking mechanism, pressure is applied to thelace 206 to maintain the position of thelace 206 until a user releases thelocking mechanism 304. -
FIG. 3B depicts a wind-and-tuck mechanism 300B that may be implemented as a lace tensioner. To apply tension to thelace 206, the user winds ahandle 306, which retracts thelace 206. The user then tucks thehandle 306 into areceiver 308 that prevents thehandle 306 from un-winding. The tension is maintained until a user removes thehandle 306 from thereceiver 308. -
FIG. 3C depicts ajam cleat 300C that may be implemented as a lace tensioner. To apply tension to thelace 206, the user pulls on ahandle 310 connected to thelace 206. Acleat 312 allows thelace 206 to move through thecleat 312 in one direction but prevents movement in the opposite direction. Thus, the tension is maintained until a user releases thecleat 312. - Referring back to
FIG. 2 , thelace 206 may be composed of various materials and/or may include a coating composed of various materials. Selection of material for thelace 206 and/or the material for the coating may be based on thelace tensioner 204. Somelace tensioners 204 may be geared to increase the tension in thelace 206. In these and other embodiments, the material for thelace 206 and/or the coating may be selected to withstand the tension. - Additionally or alternatively, the material of the
lace 206 and/or the coating may be selected to affect friction between thelace 206 and thelace retainers 208. As thelace 206 is drawn through thelace retainers 208, there may be some advantages of having friction between thelace retainer 208 and thelace 206. For instance, friction between thelace 206 and thelace retainer 208 may result in sequential tightening which is described with reference toFIGS. 4A and 4B , while reducing friction between thelace 206 and thelace retainer 208 may result in a more even tension between thelace retainers 208. - In the depicted embodiment, the
lace retainers 208 are U shaped. Specifically, each of thelace retainers 208 includes aninlet 214, anoutlet 216, and alength 218. Theinlet 214 and theoutlet 216 are oriented substantially perpendicular toedges 220 of thefirst portion 210. Thelength 218 is oriented substantially parallel to theedges 220 of thefirst portion 210. InFIG. 2 , theinlet 214, theoutlet 216 and thelength 218 are labeled on onelace retainer 208, however each of thelace retainers 208 include an inlet, anoutlet 216 and alength 218. - In some embodiments, the
lace retainers 208 positioned on thefirst portion 210 are staggered with respect to thelace retainers 208 positioned on thesecond portion 212. In these and other embodiments,inlets 216 of thelace retainers 208 on thefirst portion 210 may be positioned across theseparation 202 fromoutlet 212 of thelace retainers 208 on thesecond portion 212. Alternatively, thelace retainers 208 positioned on thefirst portion 210 may be positioned directly opposite acorresponding lace retainer 208 positioned on thesecond portion 212. - A
first distance 224 may be defined between any one of thelace retainers 208 on thefirst portion 210 and any one of thelace retainers 208 on thesecond portion 212. Additionally, asecond distance 226 may be defined between any one of thelace retainers 208 on thefirst portion 210 and any other,adjacent lace retainers 208 on the first portion or between any one of thelace retainers 208 on thesecond portion 212 and any other,adjacent lace retainers 208 on thesecond portion 212. Thefirst distance 224 and thesecond distance 226 may vary between embodiments and may vary on a single embodiment. For example, afirst distance 226 and asecond distance 224 may include one inch near theedge 220 and two inches farther from theedge 220. This may create differing pressures in different areas when thetightening mechanism 200 is operated. When thelace retainers 208 are closer together (i.e., the first and/orsecond distances lace retainers 208 are farther from one another, less pressure may result. Additionally, the number oflace retainers 208 may vary between embodiments. The number oflace retainers 208, thefirst distance 224 and thesecond distance 226 may be selected to create areas of high tension and areas of low tension, to create different areas of mobility, etc. - The
tightening mechanism 200 may also include alace conduit 222. Thelace conduit 222 is coupled to thelace tensioner 204 at one end and routes thelace 206 to theedge 220 of thefirst portion 210. Thelace conduit 222 may be configured to such that thelace tensioner 204 may be positioned in a convenient location on thefirst portion 210. Additionally, thelace conduit 222 can be configured such that thelace 206 exits thelace conduit 222, extends across theseparation 202, and enters one of thelace retainers 208. - In some embodiments, the
lace conduit 222 may be configured such that thelace 206 extends across theseparation 202 at a substantially right angle to theedge 220 of thefirst portion 210. -
FIGS. 4A-4C illustrate an example sequential tightening process that may be implemented by thetightening mechanism 200 ofFIG. 2 . Accordingly, some of the components described with respect toFIG. 2 are included inFIGS. 4A-4C . Description of these components is not repeated with reference toFIGS. 4A-4C . -
FIGS. 4A-4C illustrate a sequence ofviews 400A-400C of thetightening mechanism 200 ofFIG. 2 as tension is applied to alace 206.FIG. 4A illustrates afirst view 400A in which thetightening mechanism 200 has little or no tension applied to thelace 206.FIG. 4B illustrates asecond view 400B in which thetightening mechanism 200 has some tension applied to thelace 206.FIG. 4C illustrates athird view 400C in which thetightening mechanism 200 has a tension applied and maintained. -
FIGS. 4A-4C include auser 402 and a cryotherapy system is fit to a leg of theuser 402. The leg of theuser 402 is oriented inFIGS. 4A-4C such that a core of theuser 402 is above (i.e., at the top of each ofFIGS. 4A-4C ) the cryotherapy system. Thelace retainers 208 include one or moreproximate lace retainers 404 positioned nearest the core of theuser 402 and one or moredistal lace retainers 406 positioned farthest from the core of theuser 402. - As shown in
FIG. 4B , when the tightening mechanism applies tension to thelace 206, thedistal laces 406 retainers move together before theproximate lace retainers 404. Accordingly, an exterior pressure is applied first to theuser 402 away from the core of theuser 402. The tension is sequentially applied,distal-most lace retainers 406 toproximate-most lace retainers 404. As depicted inFIG. 4C , once the tension is applied and maintained, the external pressure becomes uniform. - By applying tension in a distal-to-proximal fashion, namely, from a portion of the anatomy of the user most remote from the core of the user to a portion of the anatomy of the user relatively nearer to the core of the user, embodiments of the tightening mechanism can facilitate healing and/or recovery processes.

FIGS. 5A and 5B illustrate implementation of anexample foam pad 502 in thecryotherapy system 100 ofFIGS. 1A-1D .FIG. 5A include components (e.g., 102, 200, 112, 116, 114, 106, 118, 110, and 108) described with reference toFIGS. 1A-1D . Descriptions of these components are not repeated with reference toFIG. 5A . - It should be noted that embodiments of a foam pad, such as
foam pad foam pad 502 andfoam pad 506. In some instances, an embodiment of the invention can be provided with a packet of smaller pads of various shapes and sizes that a user can use to customize the device to his or her particular anatomy. For example, a knee joint includes a variety of different shapes and surfaces, and one or more different pads, such as a pad having a butterfly shape for example, can be placed at the appropriate locations of the device to ensure that all of the shapes and surfaces of the knee joint are compressed at substantially the same time, and with substantially the same magnitude of compressive force, as other parts of the anatomy with which the device is in contact. - These pads can be of a material that is relatively easy to cut, such as with scissors. Additionally, the pads can be configured to be removably attached to a portion of the device, such as by a hook-and-loop type of material, so that they can easily be relocated to suit another user. In one alternative embodiment, the pads are permanently affixed to a layer of the device, such as by sewing. In this alternative, the pads can be located within the layer or on the outside of the layer. The layer that carries the pads can be the compression layer, or can be another layer located between the compression layer and the anatomy of the user.
- Generally, the
foam pad 502 acts to concentrate the external pressure to areas, which due to the natural shape of extremities, may otherwise not receive sufficient compression or thermodynamic transfer. With combined reference toFIGS. 5A and 5B , thefoam pad 502 may includemultiple thicknesses 504A-504C (generally thicknesses 504) and/or ahole 506.

The devices can be attached together using mechanisms such as zippers, hook-and-loop type closures, and/or any other securing device that permits removable attachment of the devices to each other, including the example securing devices disclosed herein. - With attention now to
FIG. 20 , details are provided concerning a thigh-to-ankle cryotherapy system, one embodiment of which is denoted at 1400. Except as noted below, the thigh-to-ankle cryotherapy system 1400 may be similar, or even identical, in construction and operation to any of the other embodiments disclosed herein. - As noted above, embodiments of the invention can be configured to fit any portion, or portions, of the anatomy of a user. Similar to other embodiments disclosed herein, the thigh-to-ankle cryotherapy system 1400 optionally includes one or more thermal packs (not shown in
FIG. 20 ), examples of which are disclosed herein. - As well, the thigh-to-ankle cryotherapy system 1400 may include an outer layer 1402 having portions 1402A and 1402B, one or both of which are movable relative to each other and to an inner layer 1404. As disclosed elsewhere herein, the inner layer 1404 may be omitted in some embodiments. Moreover, the inner layer 1404, when present, and outer layer 1406 may be constructed in the same manner and with the same materials as disclosed in any of the other embodiments of layers disclosed herein.
- With continued reference to
FIG. 20 , the thigh-to-ankle cryotherapy system 1400 includes one or more tightening systems, such as tightening systems 1406 and 1408 for example. The tightening systems 1406 and 1408 may be similar, or identical, to each other, but that is not required. The tightening systems 1406 and 1408 can be any of the example tightening systems disclosed herein. In the particular example ofFIG. 20 , the tightening system 1406 is configured and arranged to tighten a lower portion of the outer layer 1402, while the tightening system 1408 is configured and arranged to tighten an upper portion of the outer layer 1402. From a therapeutic perspective, at least, it may be advantageous to first tighten the lower portion of the outer layer 1402, and subsequently tighten the upper portion of the outer layer 1402. Moreover, the use of a plurality of tightening systems in this embodiment lends a high degree of customization to the user/therapist in terms of the amount of compression applied to different parts of the anatomy of the user. In fact, some embodiments may include more than two tightening systems, while other embodiments employ only a single tightening system. Finally, while the example ofFIG. 20 indicates that the tightening systems 1404 and 1406 are operable from a location near an upper thigh of the user, it should be understood that the tightening systems 1404 and 1406 can be configured to be operated from other locations as well, and the scope of the invention is not limited to the particular arrangement depicted inFIG. 20 . - Turning finally to
FIG. 21 , details are provided concerning a cryotherapy garment, an example of which is denoted at 1500. Except as noted below, thecryotherapy garment 1500 may be similar, or even identical, in construction and operation to any of the other embodiments disclosed herein. - In the example of
FIG. 21 , thecryotherapy garment 1500 is generally in the form of a pair of pants that a user can wear over bare skin, or over clothing, although thecryotherapy garment 1500 could take other forms as well, such as a shirt or portion thereof, or a garment that fits around the trunk of a user, possibly in the form of a vest for example. Thecryotherapy garment 1500 has a wide range of applications and may, for example, be particularly useful to endurance athletes such as runners, skiers or cyclists for example, after having competed in an event lasting several hours or more. However, thecryotherapy garment 1500 can be used by other types of users, as well in a variety of therapeutic applications. Theexample cryotherapy garment 1500, like the other embodiments disclosed herein, may be easier to use and more effective than inflatable devices, and may also enable a much higher degree of mobility to the user. - As well, the
cryotherapy garment 1500 may include anouter layer 1502 havingportions inner layer 1504. The movable portion(s) of the layers on one leg may optionally be attached to the movable portion(s) of the layers on the other leg. For example, theouter layer 1502 may have a total of only two pieces of material, one on the front of the legs of the user and one on the back of the legs of the user. In an alternative embodiment, theouter layer 1502 may have a total of four different pieces of material, one each on the front of each leg and one each on the back of each leg. The front pieces in this example are not attached to each other, nor are the back pieces attached to each other. More generally, thecryotherapy garment 1500, like the other embodiments disclosed herein, can be constructed with any number of different pieces of material. A relatively greater number of layer pieces and/or tightening mechanisms may enable, for example, a relatively high level of customization of the amount of compression that is applied to various parts of the anatomy of the user. It should be noted that aninner layer 1504, if present, can be constructed in any of the aforementioned configurations discussed in connection with theouter layer 1506. - As disclosed elsewhere herein, the
inner layer 1504 may be omitted in some embodiments. Moreover, theinner layer 1504, if present, andouter layer 1502 may be constructed in the same manner and with the same materials as disclosed in any of the other embodiments of layers disclosed herein. - With continued reference to
FIG. 21 , thecryotherapy garment 1500 may include first andsecond tightening systems cryotherapy garment 1500. With this configuration, a user is able to impose a level of compression on one leg that is different from a level of compression imposed on the other leg, or a user can apply about the same level of compression to both legs. It should be noted that while theexample cryotherapy garment 1500 includes a single tightening system on each leg, each of the legs could alternatively be configured with two or more tightening systems, in a configuration which could be similar to that disclosed inFIG. 20 , for example. Thetightening systems FIG. 21 indicates an arrangement where thetightening systems outer layer 1502 first from a distal location, namely, near the feet or ankles of a user, and subsequently toward a proximal location, namely, near an upper thigh of waist of a user. Applying compression in this order may provide desirable therapeutic effects, though it should be understood that one or more of thetightening systems - As in the case of the other embodiments disclosed herein, the
cryotherapy garment 1500 may include one or more thermal packs and/or other therapeutic devices. These devices, as is the case with other embodiments disclosed herein, can be configured and arranged to suit the general, and specific, anatomy of a user. As an example of the former, it may not be necessary or desired to include such a device on all portions of the inside front portions of the lower legs since much of that area is bone rather than muscle. However, therapeutic devices could be included in these areas if desired. - All examples and conditional language recited herein are intended for pedagogical objects to aid the reader in understanding the invention and the concepts contributed by the inventor to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Although embodiments of the present inventions have been described in detail, it should be understood that the various changes, substitutions, and alterations could be made hereto without departing from the spirit and scope of the invention.
- It should be appreciated with the benefit of this disclosure and the numerous example embodiments described herein, the cryotherapy systems (e.g., 100, 600, 900, 1000, and 1100) may include one or more components, features, systems, etc. as described above in any combination. Thus, a particular configuration may include one or more components not explicitly shown together without limitation.
- As will be apparent from the disclosure, one or more embodiments of the invention, such as the
cryotherapy system 100 for example, can provide one or more advantageous and unexpected effects, in any combination, some examples of which are set forth below. It should be noted that such effects enumerated herein are neither intended, nor should be construed, to limit the scope of the claimed invention in any way. - By way of illustration, one or more embodiments of the invention may be advantageous inasmuch as they enable a user to combine cold therapy and compression in a single easily portable device.
- As well, one or more embodiments may be advantageous in that they combine cold therapy and compression capabilities in a single device that is lightweight and portable and requires no external support systems or components.
- Further, one or more embodiments of the device may be advantageous in that they can enable a user to quickly and easily adjust a compressive force exerted by the device on an injured, or otherwise affected, portion of the anatomy of the user, and such adjustments can be made without having to reposition the device on the anatomy of the user.
- Additionally, one or more embodiments of the invention may be advantageous relative to inflatable devices that are sometimes used to apply compression to an affected portion of the anatomy of a user, in that such embodiments effect compression, and release of compression, by employing relative translational motion between elements of the device, while inflatable devices typically rely on concentric elements that do not change position relative to each other in use, or preparatory to use. Correspondingly, one or more embodiments of the invention become relatively smaller in circumference as increased compression is applied, while inflatable devices, by their nature, necessarily increase in circumference as increased compression, effected by greater inflation, is applied. The relatively smaller profile of such embodiments of the invention may enable, among other things, enhanced mobility of the user.
- As well, and disclosed herein, a single embodiment of the invention can exert compressive forces of varying magnitude on different portions of the anatomy of a user. In contrast, inflatable devices typically lack this capability since the air pressure is the same everywhere in the inflatable device.
- Further, the compressive force imposed by an embodiment of the invention is easily adjusted to increase, or decrease, in magnitude. In contrast, an inflatable device can be adjusted to reduce an imposed compressive force by releasing air or another gas from the inflatable device. However, once such an adjustment is made, it may be inconvenient, difficult, or impossible to re-inflate the device in order to increase the magnitude of an exerted compressive force.
- Embodiments disclosed herein may also be advantageous in that they do not require an inflation device or inflatable bladder. Inflation devices may be unreliable and may require a significant amount of time to effect inflation of a bladder. As well, any inflatable item is susceptible to punctures that can render it non-functional.
- The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
